hello again to this great forum. questions on a vermont castings auger motor. our auger is not feeding, we have checked the motor and it humms and the fan on the back of the motor starts to turn but then stops. question is does the humming mean that the motor works? and the auger is jammed? (the stove is totally cleaned all pellets removed and used a air compresser to blow all the debris out of the chute) any help is greatly appreciated. thanks the quints
